To use a crystal all you need are a couple of small capacitors. I agree that a resonator is easier, and if you have some, use them. I've generally used a 10 MHz resonator with the built-in 4xPLL for 40 MHz. Good luck! -- D. Jay Newman ! Pudge controls the weather. jay@sprucegrove.com ! http://enerd.ws/~jay/ ! Oh good.
